What do you know about skin? In fact, students from 6th grade of primary can say they know a lot. For the last 3 weeks they’ve been using a cooperative learning strategy called Expert groups. They’ve worked in little groups preparing an original, different and not common presentation of their theories and then they have represented and explained it to the rest of the class while they were taking notes. The final work has been incredible, they are much more creative than you can imagine. So… at the end, they have all become experts in skin. Ask them, you’ll see!
